NOTE
• The operation command coming from GPI/O port will be canceled when the projector is processing other
tasks, such as lamp cooling and switching title.
• Set all other pins than those in use to “OFF”.
• The operation command is executed upon continuous input of the “ON” pulse for approximately 200 ms.
